Mighta been an equation mix up. I only know cause I still use those blasted sin/cos/tan equations a ton on a daily basis.

Chopping off 1" of a stick at lie 5 (45 degrees) means you change the height of the hand by 0.707".

The higher the lie, the more it affects your hand height when you cut it.

My Datsyuk is a 6 lie. The shaft is 55" long butt to heal. Rested against a wall with the blade flat (in the middle of the blade bottom), the butt is about 42" high from the ground. That means the angle y is about 49 degrees, the x angle 131 degrees. Which means the

*measured* lie is around be 7, pretty close.
